Struct InvalidInputError 

pub struct InvalidInputError { /* private fields */ }

Caller-supplied input did not satisfy SMTP grammar.

The error carries a static reason string and never echoes the offending input, which would risk leaking message content or credentials into logs.

Implementations

impl InvalidInputError

pub const fn new(reason: &'static str) -> Self

Construct from a static reason. Reasons are static to make it statically impossible to embed runtime-supplied user input.

pub const fn reason(&self) -> &'static str

The reason string.

Trait Implementations

impl Debug for InvalidInputError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for InvalidInputError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for InvalidInputError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<InvalidInputError> for SmtpError

fn from(value: InvalidInputError) -> Self

Converts to this type from the input type.
